<PHYSICAL_UNIT>Dimap_Generic 1.0

Physical measure unit for the spectral band being described

Description :

This record provides the unit of the physical value resulting from data radiometric count to physical measure conversion such as Illumination or height :

L = X/A + B

where:

  • L is the resulting physical value expressed in PHYSICAL_UNIT
  • X is the radiometric value at a given pixel location as stored in the raster file (unitless).
  • A is the gain (PHYSICAL_GAIN)
  • B is the bias (PHYSICAL_BIAS)
